Download or read book Initial Electron-beam Characterizations for the Los Alamos APEX Facility written by and published by . This book was released on 1991 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing upgrade of the Los Alamos Free-Electron Laser (FEL) Facility involves the addition of a photoelectric injector (PEI) and acceleration capability to about 40 MeV. The electron-beam and high-speed diagnostics provide key measurements of charge, beam position and profile, divergence emittance, energy (centroid, spread, slew, and extraction efficiency), micropulse duration, and phase stability. Preliminary results on the facility include optical transition radiation interferometer measurements of divergence (1 to 2 mrad), FEL extraction efficiency (0.6 {plus minus} 0.2%), and drive laser phase stability (

Book excerpt: The Los Alamos free electron (FEL) laser oscillator has successfully operated over a wavelength range from 9 to 11 .mu.m with a peak output power of 5 MW and an average output power of 6 kW over a 70-.mu.s pulse length. The FEL is driven by a conventional rf linear accelerator operating at 1.3 GHz with a nominal energy of 20 MeV. Particularly important parts of the beamline are the electron gun, the subharmonic and fundamental-bunching systems, the accelerator, the feedback controllers, the steering and focusing systems, the Cherenkov radiators used as beam-position monitors, and the slow and fast deflectors used with the diagnostic spectrometer at the exit of the beamline. We will discuss problems and present the performance of these components. 10 references, 12 figures, 2 tables.

Download or read book On-line Electron Beam Measurements for the Los Alamos Free-Electron Laser written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in the electron beam diagnostics used on the Los Alamos Free-Electron Laser (FEL) have extended our on-line, quantitative analysis capability to extraction efficiency and micropulse temporal duration. The FEL's 20-MeV electron beam is 100 .mu.s in length and consists of approx. 2000 micropulses of 20-ps duration and 46-ns separation. This extreme range of time scales is addressed by employing a combination of synchronized beam deflectors, an electron spectrometer, intensified video cameras, real-time video digitizers, and microcomputers. The tapered wiggler result for extraction efficiency (2%) and results for pulse duration measurements (10 to 15 ps) by two techniques are presented.

Download or read book High-brightness Electron Beam Diagnostics at the ATF. written by and published by . This book was released on 1996 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Brookhaven Accelerator Test Facility (ATF) is a dedicated user facility for accelerator physicists. Its design is optimized to explore laser acceleration and coherent radiation production. To characterize the low-emittance, picoseconds long electron beam produced by the ATF's photocathode RF gun, we have installed electron beam profile monitors for transverse emittance measurement, and developed a new technique to measure electron beam pulse length by chirping the electron beam energy. We have also developed a new technique to measure the ps slice emittance of a 10 ps long electron beam. Stripline beam position monitors were installed along the beam to monitor the electron beam position and intensity. A stripline beam position monitor was also used to monitor the timing jitter between the RF system and laser pulses. Transition radiation was used to measure electron beam energy, beam profile and electron beam bunch length.

Download or read book Further Time-resolved Electron-beam Characterizations with Optical Transition Radiation written by and published by . This book was released on 1992 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-resolved characterizations of electron beams using optical transition radiation (OTR) as a prompt conversion mechanism have recently been extended on the Los Alamos Free-electron Laser (FEL) facility 40-MeV linac. Two key timescales for rf-linac driven FELs are the micropulse (10 ps) and the macropulse (5 [mu]s to 1 ms). In the past we have used gated, intensified cameras to select a single or few micropulses (25 to 400 ns gate width) out of the pulse train to evaluate submacropulse effects. Recently, we have obtained some of the first measurements of micropulse bunch length (7 to 10 ps) and submacropulse spatialposition and profile using OTR and a Hamamatsu streak camera. Additionally, micropulse elongation effects and head-to-tail transverse kick effects are reported as a function of charge.
